UNITED STATES PATENT OFFICE PAINT BRUSH FERRULE Marlon F. Kowalski,Jamaica, N. Y. Application August 16, 1944, Serial No. 549,744

2 Claims.

This invention relates to ferrules for paint brushes and is particularlydirected to an improved means for effectively retaining the edgeportions of the ferrule in overlapped relation so as to secure togetherthe handle and bristle body members in permanently associated relation.

Heretofore, the opposite edge portions of paint brush ferrules have beensecured together in a variety of ways such as by a so called lock seam,by rivets, by solder, by spot welding or a combination thereof but havebeen found open-to the objection that after limited use, the moisture ofthe paint, calcimine or other substance applied by the brush causes theswelling or expansion of th'e handle and bristle setting resulting inopening up of the ferrule seam and the falling apart of the brush.

In order to overcome the above noted objection, the present inventionbroadly comprehends an improved ierrule joint which dispenses withsoldering, riveting or spot welding operations and which is soconstructed and arranged as to pre clude any possibility of the openingup of th'e seam or joint, while more specifically the inventioncontemplates a permanent joint which embodies a series of mating nestedbights stamped or otherwise formed in the overlapped edge portions ofthe ferrule for receiving therethrough a flat lock wire or metal strapand which' bights and wire or strap, when assembled, are hammered andthus distorted so as to prevent accidental or unintentional displacementof the lock Wire or strap.

With the above recited and other objects in view, the invention is setforth in greater detail in the following specication, particularlypointed out in the appended claims and illustrated in the accompanyingdrawing, in which:

Fig. 1 is a perspective veW of a paint brush embodying a. ferruleconstructed in accordance with the present invention.

Fig. 2 is an enlarged fragmentary sectional plan view takenapproximately on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary vertical sectional view takenapproximately on the line 3-3 of Fig. 2, illustrating some of the bightsand a portion of the lock wire distorted after hammering.

Referring to the drawing by characters of ref-V erence, A designates theh'andle of a paint brush which is preferably constructed of wood andBindicates the bristle body member composed of a plurality of bristlesadhered together adjacent their upper by a suitable adhesive or cement.

The ferrule C which constitutes the present invention is preferablyfashioned from sh'eet metal into the form of a band which is adapted tobe snugly fitted into surrounding relation to the base or shank portionof the handle A and the upper adhesively connected end 4of the bristlebody member B, with the inner and outer end portions I0 and II of saidsheet or band disposed in overlapping relation to form a tubularstructure corresponding approximately to the cross-sectional size andshape of the lower base or shank portion of the handle A and the upperend portion of the bristle body member B.

The overlapping end portions II'I and II of the ferrule C are providedwith a plurality of longitudinally spaced transverse parallelregistering slits, the material therebetween being alternately offsetinwardly and outwardly to provide bights or loops I2 and I3. Theinwardly offset bights or loops I2 of the inner edge portion I0 aredesigned to nest, mate or interflt with those of the outer edge portionII, while the outwardly offsetbights or loops I3 of said inneroverlapping edge portion Il) are likewise fashioned to nest, mate orinterfit with those of the outer edge portion so that, when thus nested,adjacent alternate pairs of inwardly and outwardly offset bights I 2 andI3 define a series of loops or a linear passageway for receiving aretaining element in the form of a at wire or metallic strap I4 whichelectively locks the overlapping inner and outerA end portions I0 and II of the ierrule C and precludes relative separation thereof in anydirection.

After the retaining wire or strap I4 has been inserted and severed sothat the opposite ends thereof are substantially flush' with the outerside edges of the endmost bights or loops I3, the said bightsv or loopsare hammered or pressed to such an extent as to flatten the same therebycrimping the retaining element longitudinally, as illustrated in Fig. 3th'us preventing accidental clisplacement of the same by axial movementthereof with reference to the bights or loops.

What is claimed is:

1. In a brush, a handle member, a bristle body member and means forconnecting said members consisting of a ferrule fashioned from sheetmaterial having overlapped edge portions formed with mating nestedalternating inwardly and outwardly oiTset bights dening a linearpassageway, and a retaining element extending through said passagewaywith the outwardly offset bights disposed outside of the retainingelement and the inwardly oiset bights disposed inside of said retainingelement, said bights and retaining elelength of sheet material foldedupon itself with 5 the edge portions thereof overlapped and cut bent andformed to provide a series of mating nested inwardly and outwardly oisetbights 1ocated in a direction transversely of the edge portions, and aretaining element reaved through and disposed between the inwardly andoutwardly oiset bights, said bights being distorted toward each other onthe retaining element to crimp said element for preventing itsdisplacement from th'e bights.
